We are scientists, doctors, techies and humanity lovers, with the mission of building neuroelectronic interfaces to cure brain disorders. INBRAIN harnesses the extraordinary material properties of Graphene, the world’s thinnest and nobel-prize winning material, to build safe, uninvasive and highly efficient neural solutions.  Our mission is to decode and modulate neural networks to improve people's lives As a Process  Engineer, you wll play a key role in developing, executing and transferring semiconductor and microfabrication processes into repeatable manufacturing. The position requires strong hands-on cleanroom experience and practical knowledge of wafer-level processes. The engineer will support process development, equipment activities, troubleshooting, documentation and continuous improvement across several development and manufacturing programs. You will be at the forefront of bringing advanced healthcare solutions to market, making a tangible difference in people´s lives worldwide. This position will be office-based in Bellaterra and from 2027 in Barcelona city. Main responsibilities: Development-to-Production Transfer: Support the transfer of prototype designs and processes into controlled and repeatable manufacturing, with a focus on yield improvement, process robustness, design optimization and manufacturing readiness. This includes creating and refining Bills of Materials, Bills of Process, equipment specifications, manufacturing recipes, testing protocols and work instructions. Develop, optimize and scale semiconductor and microfabrication processes, including lithography, deposition, etching, lift-off, polymer processing, cleaning, bonding and other wafer-level processes. Execute cleanroom and laboratory activities, including wafer processing, sample preparation, inspection, characterization and data collection. Troubleshoot and resolve process issues related to materials, equipment, adhesion, patterning, uniformity, contamination and process integration. Plan and execute experiments and DOEs to establish process windows, improve yield and reduce process variability. Support equipment selection, installation, qualification, process bring-up and tool acceptance. Coordinate technical activities with external foundries, equipment suppliers, material suppliers and characterization laboratories. Apply process-control and risk-management methods, including SPC, FMEA and root-cause analysis, to improve process stability and manufacturing readiness. Prepare and maintain process documentation, technical reports, work instructions, process flows and risk assessments. Communicate process deviations, technical risks and potential delays in a timely and transparent manner. Take ownership of assigned technical activities and follow them through to completion. Work closely with cross-functional teams to support new product introduction, manufacturing scale-up and continuous improvement. Mandatory Qualifications and Soft skills: Bachelor’s or Master’s degree in Materials Science, Semiconductor Engineering, Chemical Engineering, Physics, Chemistry or a related field. At least 3 years of hands-on experience in semiconductor manufacturing , microfabrication, MEMS, wafer processing or a related cleanroom environment .
